Jalen earns $33 for babysitting 4 hours.
After how many hours of babysitting will Jalen have made over $500?
60.6 hours Jalen have made over $500.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Jalen earns $33 for babysitting 4 hours.
So, in one hour Jalen earns = 33/4
= $8.25
and, if Jalen have to made over $500 then she works
= 500/ 8.25
= 60.6 hours
Hence, 60.6 hours Jalen have made over $500.

Find y such that the slope between (2, y) and (5, -3) is 7.
Answer:
y= -24
Step-by-step explanation:
since the slope is 7 the value of y should decrease as the value of x decreases. and since you went back 3 on the x, you should go down 21 on the y resulting in -3-21 which is -24

2. Graph each inequality on a number line:
5x + 15 < 0
Answer:
x < -3
Step-by-step explanation:
1. To put this inequality on a number line, we first must solve it.
Step 1: Subtract 15 from both sides.
[tex]5x + 15 - 15 < 0 - 15[/tex] [tex]5x < -15[/tex]Step 2: Divide both sides by 5.

The face of a clock is divided into 12 equal parts. The radius of the clock face is 10 inches. Assume the hands of the clock will form a central angle. The face of a clock is divided into 12 equal parts. Which statements about the clock are accurate? Select three options. The central angle formed when one hand points at 1 and the other hand points at 3 is 30°. The circumference of the clock is approximately 62. 8 inches. The minor arc measure when one hand points at 12 and the other hand points at 4 is 120°. The length of the major arc between 3 and 10 is approximately 31. 4 inches. The length of the minor arc between 6 and 7 is approximately 5. 2 inches.
The accurate statements are:
b. The circumference of the clock is approximately 62.8 inches. c. The minor arc measure when one hand points at 12 and the other hand points at 4 is 120°. e. The length of the minor arc between 6 and 7 is approximately 5.2 inches.
The given parameters are:
[tex]n = 12[/tex] --- number of parts
[tex]r = 10[/tex] --- the radius
(a) The central angle
Between points 1 and 3, there are 2 sections, each of which has a measure of 30 degrees.
So, the measure of the two sections is:
[tex]\theta = 30^o \times 2[/tex]
[tex]\theta = 60^o[/tex]
Hence, (a) is false
(b) The circumference
This is calculated using:
[tex]C = 2\pi r[/tex]
So, we have:
[tex]C = 2 \times 3.14\times 10[/tex]
[tex]C = 62.8[/tex]
Hence, (b) is true
(c) The measure of the minor arc
Between points 12 and 4, there are 4 sections, each of which has a measure of 30 degrees.
So, the measure of the four sections is:
[tex]\theta = 30^o \times 4[/tex]
[tex]\theta = 120^o[/tex]
Hence, (c) is true
(d) The length of the major arc
Between points 3 and 10, there are 7 sections, each of which has a measure of 30 degrees.
So, the measure of the seven sections is:
[tex]\theta = 30^o \times 7[/tex]
[tex]\theta = 210^o[/tex]
The length of the arc is:
[tex]L = \frac{\theta}{360} \times 2\pi r[/tex]
So, we have:
[tex]L = \frac{210}{360} \times 2 \times 3.14 \times 10[/tex]
[tex]L = \frac{13188}{360}[/tex]
[tex]L = 36.3[/tex]
Hence, (d) is false
(e) The length of the minor arc
There is only one section between points 6 and 7
So, the measure of the section is:
[tex]\theta = 30^o[/tex]
The length of the arc is:
[tex]L = \frac{\theta}{360} \times 2\pi r[/tex]
So, we have:
[tex]L = \frac{30}{360} \times 2 \times 3.14 \times 10[/tex]
[tex]L = \frac{1884}{360}[/tex]
[tex]L = 5.2[/tex]
Hence, (e) is true

After 10 seconds on a zip line tour, you travel 50 feet. After 25 seconds, you travel 125 feet. Find the slope in feet per second
Answer:
5 feet per second
Step-by-step explanation:
Use the formula y2-y1/x2-x1. (10,50) is x1 and y1. 25 seconds and 125 feet is x2 and y2.
(125-50)/(25-10) = 75/15
We need to solve for the feet per (or 1) second, so we have to divide it by 15.
75/15= 5
So, the slope is 5 feet per second.
Which algebraic expression represents the
following situation: Six fewer seashells than
the total number of seashells in p packages,
each of which has five seashells?
Is it c
Answer:
Yes, it is c
Step-by-step explanation:
Because there are 5 seashells in p packages, you can do 5p to represent the total. There are 6 fewer sea shells, so it would be 5p-6 to represent the new situation.
Based on the information given, the equation to represent the situation is 5p - 6.
The information given is that there are six fewer seashells than the total number of seashells in p packages, each of which has five seashells.
Therefore, the equation will be:
= (5 × p) - 6
= 5p - 6.

Suppose two bicyclists start at the same location.
The first bicyclist rides due north and the other rides
due west. Find the speed that each bicyclist rode in
miles per hour if they are 8V2 miles apart after riding
for 2 hours at the same speed
Answer:
4 mi/h
Step-by-step explanation:
The distance between the cyclists is the hypotenuse of an isosceles right triangle. The hypotenuse is √2 times the length of the legs in such a triangle, so each cyclist must have ridden 8 miles in 2 hours.
Their speed is (8 mi)/(2 h) = 4 mi/h.
_____
Additional comment
Consider an isosceles right triangle with leg lengths 1. Then the Pythagorean theorem tells us the length of the hypotenuse is ...
c² = a² +b² . . . square of hypotenuse is sum of squares of legs
c² = 1² +1² . . . . both legs are 1 in our example triangle
c² = 2
c = √2
That is, the hypotenuse is √2 times the leg length.
Challenge An airplane is preparing to land at an airport. It is 36,000 feet above the ground and is descending at the rate of 3,200 feet per minute. At the same airport, another airplane is taking off and will ascend at the rate of 2,800 feet per minute. When will the two airplanes be at the same altitude and what will that altitude be? Use pencil and paper. Use two other methods to solve the problem. Explain which methods are easier to use and which are more difficult to use for the situation
They will be at the same altitude in _ minutes, when their altitude will be _ feet.
Answer:
6 seconds., 16800 feet
Step-by-step explanation:
The first plane is going y = -3200x + 36000
The second plane is going y = 2800x
Substitute the second equation for y into the first one:
2800x = -3200x + 36000
6000x = 36000 (Add 3200x to both sides)
x = 6 (Divide each side by 6000)
That means they will be the same altitude at 6 minutes.
To find how high, put your answer into one of the equations.
y = 2800 (6)
y = 16,800 feet
